Hi rr sport owners
Im wondering if anyone out there could help me because i have a fair few obd codes all at the same time. I know there are posts out there already with one code explaining what is wrong but i wondered if anybody would have an idea what to change first with all these codes showing at the same time. Any help would be great. Im not a mechanic but willing to try fixing myself.
The codes are as follows
u0132- lost communication with ride level control module.
u0100- lost communication with ecm/pcm "a"
u0133- vehicle dynamic control fail signal.
u0140- lost communication with body control module.
u0138- lost communication with terrain control module.
u0159- no communication with parking assist control module.
u0184- no communication with radio.
b1a00- control module.
b1a14- srs warning lamp.
b1a87- battery disconnection unit reset.
engine system fault.
Ps the car drives fine.
any help ???????????

Sounds like a battery issue to me maybe a battery thats about to die how old is the battery

Hi geoffsnook
I did think it may be the battery because its the original battery from 08 and i used to have an x5 which started getting suspension problems which turned out to be the battery also. I will get a new one and post my findings. Thanks

These things do throw all sorts of faults with a dead or nearly dead battery mine disco 3 did and i have just changed the battery on my sport

Hi
I wanted to post my findings and hopefully help people out on this site as it has been a great help to me. I went to see a range rover expert and he did back you up and said a lot of faults does point towards a battery but in my case he said it was 100% compressor (i forget why). I read somewhere to spray water on the pipes going into the compressor dryer to check for a leak because in between them pipes the lid cracks and sure enough there was an airline crack there (very hard to see but with water sprayed on there showed a leak). Got a new compressor dryer lid via ebay £25 and hey presto it works no warning lights. You can fit the lid without removing the compressor.

As for the engine system fault it turned out to be a stuck actuator on the turbo which i sorted for the price of a tin of wd40 and a coat hanger which is also explained on the rrsport website.
